摘要：

Free sodium ammonia clusters Na(NH3)n up to n = 45 were generated in a pickup source by injecting a beam of neutral sodium atoms into the expansion zone of a piezo driven pulsed nozzle. The clusters thus formed are studied by one-photon ionisation in the region of 266 nm to 520 nm, time-of-flight mass spectrometry as well as photoelectron spectrometry. Ionisation thresholds for clusters up to n = 18 and dissociation energies for the neutral Na(NH3)n up to n = 6 are reported.
